Industry Context

The approval of neffy addresses a significant unmet need in the treatment of anaphylaxis by providing a needle-free alternative to epinephrine injections. This aligns with a broader trend in the pharmaceutical industry towards developing more patient-friendly and convenient drug delivery systems. The market for epinephrine products is substantial, with a significant portion of patients not using their prescribed treatments correctly or at all, suggesting a large opportunity for neffy.

Comparison to Industry Standards

• EpiPen, a leading epinephrine auto-injector, has an 18-month shelf life, while neffy has a 30-month shelf life, offering a longer period of usability.
• Traditional epinephrine auto-injectors have a risk of needle-related injuries, which neffy eliminates with its needle-free design.
• Neffy's clinical trials demonstrated comparable pharmacokinetic and pharmacodynamic data to approved epinephrine injection products, suggesting similar efficacy.
• The company is targeting a co-pay of $25 for commercial patients, which is competitive with the average co-pay for epinephrine auto-injectors.
• The company is planning a commercial force of 110 representatives, which is a significant investment in sales and marketing compared to smaller pharmaceutical companies.

Stakeholder Impact

• Shareholders will benefit from the FDA approval and potential commercial success of neffy.
• Employees will be involved in the launch and commercialization of neffy.
• Patients will have access to a new, needle-free treatment option for anaphylaxis.
• Healthcare providers will have a new tool for managing allergic reactions.
• Payors will need to consider coverage for neffy.

Next Steps

• The company will launch neffy in the US within eight weeks.
• A supplemental NDA application for a 1 mg dose for children 15 to <30 kg will be filed with the FDA by the end of Q3 2024.
• The company anticipates a decision on marketing authorization for neffy in Europe in Q3 2024.
